FRIOTIO N DRAFT- RIGGING FOR RAILWAY-CARS.

SPECIFICATION f I- ming part of Letters'Patent No. 760,824, dated May24, 1904. Application filed February-18, 1904. Serial F0. 194,209. (Nomodel.)

To all whom it may concern:

Be it known that I, FREDERICK B. TOWN- 'SEND, a citizen of the UnitedStates, residing in Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Improvement in FrictionDraft-Rigging for Railway-Cars,- of which the following is aspecification. I 1

My invention relates to improvements in friction draft-rigging forrailway-cars.

My invention consists, in connection with a draw-bar and draw-barextension or draft iron in line therewith, having a straight friction:face on one side and double-incline frictionfaces oppositely disposed onits opposite or lower side, of a transversely or vertically rnovablefriction-block having double-incline friction -faces engaging thedouble-incline friction-faces on the draft-iron, a transversely-arrangedspring acting against said transverselymovable'friction-block, a pairofguide-plates to receive and hold in position a friction-plate having astraight friction-face frictionally engaging the straightfriction-surface of the draft-iron and furnished also with uprightshoulders or guides to receive, guide, and hold longitudinally inposition the transverselymovable friction-block, and a car-sillextension or housinghaving two integral limbs or members furnished withsockets to receive the ends of the car-sills and provided withshouldered recesses to receive and hold in position said guide-plates inwhich the transverselymovable friction-block works up and down,

and a spring seat or cup having an integral horizontal plate rigidlyconnected to and sup ported by the two limbs or members of the sillextension or housing, which limbs or members said plate itself connectsand braces.

My invention further consists in the novel construction of partsand'devices and in the novel combinations of parts and devices hereinshown or described. I

In the accompanying drawings, forming a part of this specification,Figure 1 is a central vertical section of a friction draft-riggingembodying my invention, the section being taken 511" line 1 1 of Fig. 2.Fig. 2 is a plan View,

friction-block.

In the drawings, A A represent longitudinal sills of the car; A, thecross-sill; A ,'the

buffer-block; A the buffer-plate, and A the carry-iron. I

B is the coupler, B the draw-bar, and B the draw-bar extension ordraft-iron, the same having-a socket or shouldered end B to receive Ithe head or shouldered end B of the draw-bar and to which it is securedby bolts or rivetsB The friction-block D has beveled corners orcorner-faces d, which engage the guide shoulders or flanges f of thestationary guideplates-F F, which guide the transversely-movablefriction-block and hold it'from longitudinal movement with the draw-barwhile permitting it to move transversely or vertically in respectthereto. The transverselymovable friction-block D is also furnished witha hollow extension rim or flange (Z at its lower end to receive andguide and hold in place the upper end of the transversely arranged andacting spring E, which bears against the lower end of thefriction-block. The transverselymovable friction-block D is alsoprovided with a longitudinal slot d to receive the vertical web Z2 whichbridgesv the inclined frictionfaces 6 b and strengthens the draft-iron.

G is the spring seat or cup, against which the lower end of the springbears, the same being also furnished with a guide portion G, which fits,receives, and guides the lower end or portion of the side casting orguide-plate V extend through the housing and both sills A A,

the housing H having an integral connecting thimble or sleeve H throughWhich the bolts extend. The sill-extension casting or housing H isfurther connected to the sills A A by vertical bolts 7& and to the frontsill A and the buffer-block A by vertical bolts 7L Longitudinaltie-rodsH also additionally anchor the sill-extension casting or housing H tothe car-framework, the housing H having integral shoulders or brackets Hto receive the tie-rod H The sill extension casting or housing H isprovided With two recesses if, each having shoulders h b to receive theupright flanges or shoulders f of the guideplates F, which are thus heldrigidly and firmly in position. The guide-plates F have overlappingflanges f at their meeting edges connected together by rivets Theguideplates F F also have shoulders ff to form a seat for, embrace, andhold in position the stationary friction-plate C. The guide-plates F areheld in place by the removable spring seat or cup G, upon the horizontalplate G of which the guide-plates F F rest. It will thus be understoodthat by simply removing the spring seat or cup G the spring,transversely-movable friction-block, draw bar, and the Wholedraft-rigging, including the guideplates F F, may be removed Whendesired for repair or replacement, While at the same time thedraft-rigging as a Whole,by reason of its cooperative action With thesill-extension easting or housing and its anchorage thereto to theinterposed guide-plates F F, is made extremely safe, strong, efficient,and durable.

In operation under either pulling or buifing strains the draft-ironmoves longitudinally With the draw-bar to which it is attached and byreason of its inclines engaging the corresponding inclines on thetransversely-movable friction-block causes the friction-block to movetransversely and compress the transversely-acting spring, and thuscushion the draw-bar by the frictional resistance due to the movement ofthe friction-surface of the draw-bar in respect to the stationaryfrictionplate. The friction of the inclined surfaces on the draw-baragainstthe corresponding inclines on the transversely-movablefrictionbloek also increases the-resistance.
